Fulgurite~
Incredibly, lightning can and does in fact create something amazing when it hits sand, but the conditions have to be perfect. When it hits a sandy beach high in silica or quartz and the temperature goes beyond 1800 degrees Celsius, the lighting can fuse the sand into silica glass. The blast of a billion Joules radiates through the ground making fulgurite—hollow, glass-lined tubes with a sandy outside. Petrified lightning.
